Actual (reported)The purpose of this research is to see if people who have had a collapsed lung that has been re-expanded can be safely taken to an elevation that a person might experience while in a commercial airplane without having their lung partially collapse again, or have any symptoms such as feeling short of breath or having oxygen levels in the blood decrease while at the simulated altitude. The investigators hypothesize that subjects who have had a collapsed lung that has been re-expanded will not have any adverse symptoms or signs while subjected to a simulated altitude of 8400 feet (565mm Hg) or 12650 ft (471mm Hg).

Actual (reported)Change in pneumothorax size
Will document pneumothorax size before simulated altitude, and size after being at simulated altitude for two hours
baseline and 2 hours
hypobaric chamber
We will use a large (26 tons) multi-place hyperbaric and hypobaric chamber at IMC in Murray, Utah (elevation 1500m or 4500ft, average ambient barometric pressure 645mm Hg). In the hypobaric study, the barometric pressure will be lowered to 554mm Hg (phase 1) or 471mm Hg (phase 2) over 20 minutes and held there for two hours.
